BACKGROUND OF THE INVENTION

This U.S. non-provisional application claims priority under 35 U.S.C. § 119 to Korean Patent Application No. 10-2004-0013427, filed on Feb. 27, 2004 in the Korean Intellectual Property Office, the contents of which are incorporated by reference herein by reference in their entirety.

1. Field of the Invention

Exemplary embodiments of the present invention relate generally to an apparatus for transferring heat and a method of manufacturing the same.

2. Description of the Related Art

Recently, with rapid distribution of information media, such as computers with semiconductor devices, semiconductor devices may be required to operate at higher speed while having higher storage capability. Accordingly, semiconductor devices may be becoming more highly integrated than ever before, which may increase the amount of heat generated from semiconductor chips. Failure to dissipate generated heat from the semiconductor chips may cause heat accumulation inside the semiconductor chips, which may adversely affect the operating reliability of the semiconductor chips.

Conventionally, generated heat from semiconductor chips may be dissipated using a heat transfer device, such as, but not limited to, a heat transfer package or a heat sink attached to the semiconductor chip. However, due to an increase in the amount of heat per unit area, the heat concentration on a small area may not be sufficiently dissipated.

To solve the above problem, a heat spreader including a cooling fluid therein for circulating the cooling fluid may be provided. However, the dimension of such a conventional heat spreader may be overly thick, thus making the semiconductor chip bulky. Accordingly, the heat spreader installed in a semiconductor chip may increase the total thickness of the semiconductor chip.

To reduce the thickness of a heat spreader, a method of adhering upper and lower plates manufactured using Micro Electro Mechanical System (MEMS) technology or a press-forming process may be used. However, in the above arrangement, there may arise problems in that leakage of a fluid flowing in a fluid channel may occur, additional adhering processes and cost may be incurred.

DETAILED DESCRIPTION OF EXEMPLARY EMBODIMENTS

Exemplary embodiments of the present invention will now be described more fully with reference to the accompanying drawings, in which exemplary embodiments of the invention are shown. However, it should be appreciated that the invention may be embodied in many different forms and should not be construed as being limited to the embodiments set forth herein; rather, the exemplary embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the concept of the invention to those skilled in the art. Throughout the specification, the same reference numerals in different drawings may represent the same element.

FIG. 1 is a flowchart that illustrates an exemplary embodiment of manufacturing a heat transfer device according to the present invention. As shown in FIG. 1, the flowchart illustrates the manufacturing process S11-S16. In S11, the binder powder may be melted; in S12, the packing structure may be formed; in S13, the metal powder may be pressed; in S14, the molten binder powder may be removed; in S15, the molten metal powder may be sintered; and in S16, the packing structure may be removed. The manufacturing of the heat transfer device will now be described in more detail by referencing FIG. 2A through FIG. 2D.

Referring to FIG. 2A, a composite material film 11 a intended for a thin film metal sintered body may include at least metal powder and binder powder which may be uniformly dispersed. It should be appreciated that other powder materials may be included in the composite material film 11 a. A region 12 a intended for a fluid channel packed with a packing material may be embedded in the composite material film 11 a. In this state, the composite material film 11 a may be heated to melt the binder powder (S11). The melting of the binder powder may increase flowability of the metal powder, which may ensure efficient binding of the metal powder.

In an exemplary embodiment, the binder powder may include a thermoplastic resin in order to provide easy melting. The thermoplastic resin used for binder powder may be, for example, polyolefin such as, but not limited to, polyethylene, polypropylene, ethylene-vinylacetate copolymer, polymethylacrylate, polybutylacrylate, polystyrene, polyvinyl chloride, polyvinylidene chloride, polyester, polyether, and/or polyvinyl alcohol. However, it should be appreciated that other thermoplastic resins may be used. The binder powder may further include a plasticizer. The plasticizer may be, for example, but not limited to, phthalic ester, adipic ester, trimeritic ester, and/or sebacic ester. However, it should also be appreciated that other plasticizer may be used.

Referring to FIG. 2B, a packing structure 12 b may be formed in the region 12 a intended for a fluid channel (S12). In an exemplary embodiment, a powder or solid packing material may be used. The packing structure 12 b may be formed by heating, for example, a thermally curable resin used as the packing material. Examples of the thermally curable resin that may be used as the packing material may include, for example, but not limited to, a phenolic resin, an urea resin, and/or an epoxy resin. In an exemplary embodiment, the thermally curable resin may be cured at a higher temperature than the melting temperature of the binder powder used as the packing material. Therefore, damage to the packing structure 12 b formed in the region 12 a intended for a fluid channel may be reduced or prevented.

In S13, the metal powder may be heated and pressed, under the condition that the packing structure 12 b has been shaped. Also, the metal powder may be pressed at the higher pressing temperature, thereby maintaining the shape of the packing structure 12 b and effectively bonding the metal powder, under the condition that the metal powder has been bonded in a desired manner by the melted binder powder after the packing material has been cured. As an exemplary embodiment, the pressing temperature of the metal powder may be higher than the curing temperature of the packing material because the metal powder may be pressed after curing the packing material, thereby maintaining the shape of the packing structure 12 b without being damaged by the melted metal powder.

In S14, the binder powder may be removed. When the metal powder is sintered after removal of the binder powder, a more precise dimension may be produced to form a thin film metal sintered body. Alternatively, it should be understood that there may be no need to completely remove the binder powder. In some cases, the removal of the binder powder may be omitted. When a thermoplastic resin is used as the binder powder, the binder powder may be removed by thermal decomposition. In an exemplary embodiment, the binder powder may be thermally decomposed at a higher temperature than the pressing temperature of the metal powder. Therefore, the binder powder may be decomposed after the pressing of the metal powder, thereby ensuring sufficient binding of the metal powder. Reference numeral 11 b may indicate a composite material film in which the binder powder may be removed after the metal powder is melted.

Referring to FIG. 2C, the molten metal powder may be sintered to form a thin film metal sintered body 11 c (S15). When the pressed metal powder is thermally sintered, the pressed metal powder may be closely contacted to each other and solidified to form the thin film metal sintered body 11 c. In an exemplary embodiment, the pressed metal powder may be sintered at a higher temperature than the decomposition temperature of the thermoplastic resin used for the binder powder. The sintering of the pressed metal powder after the removal of the binder powder may ensure efficient formation of the thin film metal sintered body 11 c.

Referring to FIG. 2D, the packing structure 12 b may be removed to form a fluid channel 12 d inside the thin film metal sintered body 1 c (S16). The packing structure 12 b made of, for example, a thermally curable resin may be removed by thermal decomposition of the thermally curable resin. In an exemplary embodiment, the thermally curable resin may be thermally decomposed at a higher temperature than the sintering temperature of the metal powder. This may result in the packing structure 12 b not being damaged during the formation of the thin film metal sintered body 11 c, which may ensure a formation of the fluid channel 12 d inside the thin film metal sintered body 11 c. A liquid cooling fluid such as, but not limited to, distilled water, methyl alcohol, an acetone, a gas cooling fluid, and/or a powder cooling fluid may be circulated through the fluid channel 12 d. It should be appreciated that other liquid cooling fluid may be used. This may result in the generated heat from a semiconductor chip provided with a thin film heat spreader to be sufficiently dissipated. Further, the fluid channel 12 d may be integrally formed with the thin film metal sintered body 11 c, unlike a method of coupling an upper plate and a lower plate to form the fluid channel. This may result in reduced or no risk of leakage of a cooling fluid circulating in the fluid channel 12 d. Furthermore, the sintering method may ensure an easier and/or less expensive procedure in manufacturing a thin film heat spreader.

In an exemplary embodiment, the thin film metal sintered body 11 c may be formed with a thickness d of approximately 0.1 to 3 mm. If the thickness of the thin film metal sintered body 11 c is too thin, then formation of the fluid channel 12 d inside the thin film metal sintered body 11 c may be difficult and leakage of a cooling fluid may occur. On the other hand, if the thickness of the thin film metal sintered body 11 c is too thick, the total thickness of a semiconductor chip provided with the thin film metal sintered body 11 c may increase. In an exemplary embodiment, the size of the thin film metal sintered body 11 c may be formed approximately as a semiconductor chip provided with the thin film metal sintered body 11 c.

In an exemplary embodiment, the fluid channel 12 d may be formed with a diameter r of approximately 0.1 to 2.5 mm. The diameter r of the fluid channel 12 d may be smaller than the thickness d of the thin film metal sintered body 11 c to reduce or prevent fracture of the thin film metal sintered body 11 c. If the diameter of the fluid channel 12 d is too small, the resistance of a cooling fluid flowing in the fluid channel 12 d may increase, which may reduce or prevent circulation of the cooling fluid through the fluid channel 12 d.

Another exemplary embodiment of manufacturing a thin film heat spreader according to the present invention will now be described with reference to FIGS. 3 through 4D.

Referring to FIG. 4A, a composite material film 21 a intended for a thin film metal sintered body may include at least metal powder and binder powder which may be uniformly dispersed. It should be appreciated that other powder materials may be included in the composite material film 11 a. A packing structure 22 a may be embedded in a region intended for a fluid channel inside the composite material film 21 a. In an exemplary embodiment, the composite material film 21 a may be heated to melt the binder powder (S21). The melting of the binder powder may increase flowability of the metal powder, which may improve binding of the metal powder.

In an exemplary embodiment, the binder powder may include a thermoplastic resin to facilitate melting. The thermoplastic resin used for binder powder may be, for example, polyolefin. Examples of polyolefin may be polyethylene, polypropylene, and ethylene-vinylacetate copolymer, polymethylacrylate, polybutylacrylate, polystyrene, polyvinyl chloride, polyvinylidene chloride, polyester, polyether, and/or polyvinyl alcohol. However, it should be appreciated that other thermoplastic resins may be used besides the ones mentioned above. The binder powder may further include a plasticizer. The plasticizer may be, for example, but not limited to, phthalic ester, adipic ester, trimeritic ester, and/or sebacic ester. However, it should also be appreciated that other plasticizers may be used.

In S22, the metal powder may be heated and pressed, under the condition that the binder powder is melted. That is, the metal powder may be pressed at the higher pressing temperature, under the condition that the initial shape of the packing structure 22 a within the metal powder is maintained and the metal powder is bonded in a desired manner by the melted binder powder, thereby maintaining the shape of the packing structure 22 b and effectively bonding the metal powder. Accordingly, the shape of the packing structure 22 a may also be maintained and the metal powder may be effectively bonded thereof. As an exemplary embodiment, the pressing temperature of the metal powders may be higher than the melting temperature of the binder powder because the metal powder is pressed after melting the binder powder, thereby effectively bonding the metal powder.

In S23, the binder powder may be removed. When the metal powder is sintered after removal of the binder powder, a thin film metal sintered body may have a more precise dimension. It should be appreciated that there may be no need to completely remove the binder powder when a sufficiently precise dimension is required. In some cases, the removal of the binder powder may be omitted. When a thermoplastic resin is used as the binder powder, the binder powder may be removed by thermal decomposition. In an exemplary embodiment, the binder powder may be thermally decomposed at a higher temperature than the pressing temperature of the metal powder. Therefore, the binder powder may be removed after the pressing of the metal powder, thereby improving the binding of the metal powder.

Referring to FIG. 4B, the molten metal powder may be sintered to form a thin film metal sintered body 21 c (step S24). When the pressed metal powder is thermally sintered, the pressed metal powder may be closely contacted to each other and solidified. In an exemplary embodiment, the pressed metal powder may be sintered at a higher temperature than the decomposition temperature of the thermoplastic resin used for the binder powder. Therefore, the sintering of the pressed metal powder may occur after the removal of the binder powder, thereby ensuring efficient formation of the thin film metal sintered body 21 c.

Referring to FIG. 4C, the packing structure 22 a may be removed to form a fluid channel 22 d inside the thin film metal sintered body 21 c (S25). In an exemplary embodiment, the packing structure 22 a may be melted at a higher temperature than the sintering temperature of the metal powder. This may result in the packing structure 22 a from being damaged during the formation of the thin film metal sintered body 21 c, which may improve formation of the fluid channel 22 d inside the thin film metal sintered body 21 c. When the packing structure 22 a is made of a metal that is melted at a higher temperature than the sintering temperature of the metal powder, a metal with a high toughness (e.g., high viscosity strength and/or high resistance to other fracture factors) may be provided. The packing structure 22 a made of a high toughness metal may be mechanically removed, which may improve formation of the fluid channel 22 d.

A liquid cooling fluid, such as, but not limited to, distilled water, methyl alcohol, and acetone, a gas cooling fluid, and/or a powder cooling fluid may be circulated through the fluid channel 22 d. It should be appreciated that other liquid cooling fluid may be used. As a result, heat generated from a semiconductor chip provided with a thin film heat spreader may be more efficiently dissipated. Further, the fluid channel 22 d may be integrally formed with the thin film metal sintered body 21 c, unlike a method of coupling an upper plate and a lower plate to form the fluid channel. This may result in low or no risk of leakage of a cooling fluid circulating in the fluid channel 22 d. Furthermore, a sintering method may provide an easier and/or less expensive procedure of manufacturing a thin film heat spreader.

In an exemplary embodiment, the thin film metal sintered body 21 c may be formed with a thickness d of approximately 0.1 to 3 mm. If the thickness of the thin film metal sintered body 21 c is too thin, then formation of the fluid channel 22 d inside the thin film metal sintered body 21 c may be difficult and leakage of a cooling fluid may occur. Alternatively, if the thickness of the thin film metal sintered body 21 c is too thick, the total thickness of a semiconductor chip provided with the thin film metal sintered body 21 c may increase. In an exemplary embodiment, the size of the thin film metal sintered body 21 c may be formed approximately as a semiconductor chip provided with the thin film metal sintered body 21 c.

In an exemplary embodiment, the fluid channel 22 d may be formed with a diameter r of approximately 0.1 to 2.5 mm. The diameter r of the fluid channel 22 d may be smaller than the thickness d of the thin film metal sintered body 21 c to prevent fracture of the thin film metal sintered body 21 c. If the diameter of the fluid channel 22 d is too small, then the resistance of a cooling fluid flowing in the fluid channel 22 d may increase, which may reduce or prevent circulation of the cooling fluid through the fluid channel 22 d.

A heat spreader manufactured by the above-described exemplary embodiments will now be described with reference to FIG. 5, which is a perspective view of a thin film heat spreader according to an exemplary embodiment of the present invention.

Referring to FIG. 5, a thin film heat spreader according to an exemplary embodiment of the present invention may include at least a thin film metal sintered body 1 and a fluid channel 2. The fluid channel 2 may pass through inside the thin film metal sintered body 1 so that a cooling fluid may flow in the thin film metal sintered body 1. In an exemplary embodiment, the fluid channel 2 may be formed in an elongated and curved shape so that a liquid cooling fluid, such as, but not limited to, distilled water, methyl alcohol, acetone, a gas cooling fluid, and/or a powder cooling fluid may contact with a wider inner surface area of the thin film metal sintered body 1. It should be appreciated that other liquid cooling fluid may be employed. This results in the generated heat from a semiconductor chip provided with a thin film heat spreader to be efficiently dissipated.

In an exemplary embodiment, the thin film metal sintered body 1 may be formed with a thickness d of approximately 0.1 to 3 mm. If the thickness of the thin film metal sintered body 11 c is too thin, then formation of the fluid channel 12 d inside the thin film metal sintered body 11 c may be difficult and leakage of a cooling fluid may occur. Alternatively, if the thickness of the thin film metal sintered body 11 c is too thick, the total thickness of a semiconductor chip provided with the thin film metal sintered body 1 may increase. In an exemplary embodiment, the size of the thin film metal sintered body 1 may be formed approximately as a semiconductor chip provided with the thin film metal sintered body 1.

In an exemplary embodiment, the fluid channel 2 may be formed with a diameter r of approximately 0.1 to 2.5 mm. The diameter r of the fluid channel 2 may be smaller than the thickness d of the thin film metal sintered body 1 to prevent fracture of the thin film metal sintered body 1. If the diameter of the fluid channel 2 is too small, the resistance of a cooling fluid flowing in the fluid channel 2 may increase, which may prevent efficient circulation of the cooling fluid through the fluid channel 2.

Exemplary embodiments of the present invention relate to a thin film heat spreader which may reduce or prevent leakage of a fluid flowing therein and a method of manufacturing the same. More particularly, exemplary embodiments of the present invention may provide a thin film heat spreader for reducing or preventing leakage of a fluid flowing therein, and an easier and/or less expensive method of manufacturing the thin film heat spreader.

Exemplary embodiments describe the composite material film having “uniformly” dispersed metal powder and binder powder. However, it should be understood that the metal and binder powders may be dispersed in other manner, such as consistently, regularly, homogenously, evenly, and/or equivalently. It should be appreciated that the powders may also be uniformly dispersed sporadically or evenly spaced. It should further be appreciated that the dispersed powders may be uniformly dispersed merely on a portion of the composite material film and/or the entire film.
